I don't know why built-in spectrometer is a huge advantage to you.
I have 5 printers working in my lab ( 1 Z3200)
I have an i1pro which I use that for all of my printers besides the z3200.
of cuz, the z3200 broke down few times and i STILL have my i1 to make everything work.
also, what if I have 5 Z3200, that means I have 5 spectro in one location?
I dont that that is necessary at all
Your lab is a big outfit Aaron. For the on again, off again printer, the spectrometer is perfect. I have no use for another 44" printer, and only have an Epson 4800 Pro for sheet fed work, all of which I have had custom profiles made. I don't want to futz with profile making devices - the Z3100 was/is perfect in that regard. It's one of the strong points of the printer, in addition to the drip system which keeps clogs in check. I'm talking about use for an artist who is doing their own work. Granted, my studio is 15,000 sq. ft., and hypothetically, having a few Z3100s spread out, in different rooms, a spectrometer in each machine would be pretty nice. (Remember, an artist (not a lab) can fool around with being super picky about the work. I usually make a custom profile on my Z3100 frequently, mainly because the humidity conditions are constantly changing in this large loft, and also, because it's just easy with the Z3100. No brainer easy.) Most labs keep their printers bundled in one room, close together, but an independent artist may not necessarily do it that way. We all have different requirements, and I understand yours. Thanks for your comments -
